Convert the address to your own public IP address.

2 is a view schematically showing the configuration of a home gateway system according to the present invention. As shown in FIG. 2, the home gateway system 200 includes a data transmission / reception module 210 for transmitting and receiving data signals of an internet network communication or a local network communication, and a network communication data signal input / output to the data transmission / reception module 210. An IP address conversion unit 220 for converting an IP address of the power transmission module 220 connected in parallel with the data transmission / reception module 220 and switching to a power mode or a power saving mode depending on whether a communication data signal is received ( 230).

The data transmission / reception module 220 includes an external network interface for forming a communication channel for connecting with the external Internet and a home network interface for forming a communication channel for connecting with a home network.

The IP address conversion unit 210 converts the public and private IP addresses input from the public IP layer and the private IP layer of the data transmission / reception module to each other and relays the packet transmission. That is, the public IP layer uses dynamic public IP addresses, and the private IP layer uses private IP addresses.

The power standby switching module 230 reduces the power consumption during standby by switching the data transmission / reception module to a power saving mode when the standby mode is switched to the standby mode.

3 is a diagram schematically illustrating a configuration of the power standby switch module of FIG. 2. As shown therein, the power standby switching module 230 includes: a communication traffic detector 310 detecting a communication data signal reception state received from the data transmission / reception module 220; A temporary data storage unit 320 for storing a data signal according to the importance of the communication data signal detected by the communication traffic detector 310; A standby mode controller 330 for setting the communication traffic detector to a sensing enhanced mode according to a reception state of the communication data signal sensed by the communication traffic detector 310 and transmitting a control signal for switching the standby mode; It is configured to include a power mode switching unit 340 for switching to a standby mode or a power mode by the control signal of the standby mode controller 330.

The communication traffic detector 310 detects the presence or absence of a data signal and a data type of the received communication traffic data, and distinguishes according to the importance of the data signal in the enhanced sensing mode.

The temporary data storage unit 320 stores the important data signal received when the communication traffic detector 310 switches to the enhanced sensing mode.

The standby mode controller 330 controls the power mode switching unit 340 to switch to the standby mode and to the enhanced detection mode of the communication traffic detector. In addition, the data transmission / reception module is switched to a power saving mode.

The power mode switching unit 340 switches the power standby switching module 230 to the standby mode or the normal mode according to the control signal of the standby mode controller 330.

Looking at the operation of the power standby switching module 230, the communication traffic detection unit 310 is connected to the data line with the data transmission and reception module 220 to detect the presence and data type of communication data received. When the communication traffic detection unit 310 transmits the presence or absence of communication data and the type of data to the standby mode controller 330, the standby mode controller 330 is a power mode switching unit when there is no transmission / reception data on the communication line for a predetermined time.

4 is a flowchart illustrating a method for reducing power consumption of a home gate system according to the present invention. As shown in FIG. 4, first, after receiving a basic setting value (S410), a step of monitoring communication traffic of data transmitted and received by the data communication unit for a predetermined time is performed (S420).

That is, when the standby mode control unit 330 starts to receive data values from the communication traffic detection unit 310, in the initial state, the default value is applied to the entire standby mode switching module 230 and the traffic on the network is transmitted and received. Start monitoring.

In operation S430, the method determines whether data of the communication traffic is present and switches to a standby mode when there is no data (S440). Here, if there is traffic on the network for a certain period of time, if the data still exists, the traffic monitoring mode is maintained, but if there is no network traffic is switched to the standby mode.

Then, after switching to the standby mode, switching to the enhanced communication traffic detection mode is performed (S450). That is, when the standby mode is switched, the standby mode controller 330 commands the power mode switch 340 to switch the data transmission / reception module 220 to the power saving mode and only the communication traffic detector 310 receives data. In this case, the standby mode controller 330 activates the temporary data storage 320 and switches to the enhanced communication traffic detection mode.

Next, the step of storing and analyzing the data received in the enhanced communication traffic detection mode is performed (S460). That is, in the enhanced traffic detection mode, the data is stored in the temporary data storage 320 and analyzed at the same time.

Next, a step of determining whether or not the analyzed data is important is performed (S470). At this time, the analyzed data is to distinguish the importance of the data compared to the preset value, and if the data is not important to maintain the enhanced communication traffic detection mode (S480).

On the other hand, if the importance of the analyzed data is high (S490) and the step of switching to the normal mode is performed (S500). Here, when important data is generated, the important data is transmitted to a main unit (not shown) for processing.

Then, the normal mode is switched to the enhanced communication traffic mode is switched to the normal traffic mode to determine only the presence or absence of data, the power mode switching unit 340 powers the data transmission and reception module 220 in the standby mode Return to normal mode.

Therefore, by using the network traffic based power consumption reduction home gateway system, the corresponding communication block is switched to the power saving mode and the standby mode according to the network traffic, thereby reducing the power consumption.
